In Switzerland, highway noise barriers surrounding the Oberland Autobahn near Wangen-Brüttisellen will soon provide solar power.

Last year, Switzerland’s Federal Roads Office made the surfaces of highway noise barriers free and set out to cover 350 of them in solar panels. Swiss officials estimated that the arrays could generate 100 gigawatt hours of clean energy per year, CleanTechnica reported.

The project is now kicking off with the first two privately owned solar arrays for the A15 Oberland motorway, which will be completed over the first half of 2025. As TA Zurich reported, these photovoltaic installations are expected to provide about 500,000 kilowatt hours of electricity per year.

The first solar arrays will be operated by Lima Solar AG, which has had to overcome several hurdles before starting the installation, including finding low-cost, low-glare panels that won’t distract drivers.

However, despite the hurdles, the company has now paved the way for other noise barrier solar projects to move forward at a faster pace.

One ongoing challenge involves connecting the private solar arrays to the electric grid, particularly in more rural areas, and establishing a marketplace for the generated power. As TA Zurich reported, covering the noise barriers alone would only provide a limited amount of clean energy for residents.

However, Switzerland passed a law in 2023 requiring new buildings with 3,300 square feet (300 meters) or more of roof space to install solar panels. In 2024, Zurich passed a law requiring solar panels on buildings, new or old, with roofs at least 3,300 square feet by 2040.

By installing more panels in already developed spaces that are otherwise unused, Switzerland is incorporating more efficient and affordable ways to install solar.

There has been promising research on the benefits of adding photovoltaic installations along highways to power local communities and support EV charging infrastructure.

A study published in November 2023 found that deploying solar panels on highway noise barriers along highways in the Netherlands could provide around 200 gigawatt hours per year of energy. Further, the study determined that solar energy along highways, both on noise barriers and on public lands around highways, could supply enough power for highway EV charging stations to charge more than 300 electric vehicles per day, which would meet about 80% of expected demand by 2030.

According to a study published in August 2024, installing solar panels overtop of highways could be an effective way to reduce both emissions and traffic accidents. The report found that installing highway solar panels globally could reduce carbon emissions by about 28%. By putting solar arrays over highways, the researchers of that study estimated a reduction in global traffic deaths by about 10.8%, because the solar panels would protect the highways from precipitation.

As the project along the Oberland Autobahn revealed, there are still challenges to low-glare solar panel costs and delayed governmental approval processes, but as more companies work to establish these types of systems, the cost and time to complete the projects is expected to decline.

Cybersecurity is about more aspects of ESG than just governance

Cybersecurity is about more aspects of ESG than just governance

Security operations teams must increasingly do their bit to help their employers achieve environmental targets, which may require some system and strategic changes.

For several years now, annual sustainability reports by listed Australian companies have provided a window into cybersecurity strategies employed at these companies. But in spite of the report name, there is often no link between security and sustainability in the information presented.

As these reports cover environmental, social and governance (ESG) practices, addressing cyber risks comes under the governance piece. Yet, the security team — through its choices of hardware, software and services — has a contribution to make on the sustainability front as well.

It is commonly acknowledged that IT infrastructure and data centres are large energy users. Teams in these spaces have worked to become more efficient: rightsizing infrastructure provisioning to fit workloads, utilising more renewable energy sources, hosting equipment in data centres that are rated to be efficient with power and water consumption and the like.

That same level of investment and effort is yet to be brought to bear on the work of the security team and their technology stack. One reason for this is likely to be the intense pressure that security teams are under to protect ever-increasing attack surfaces and ward off a constantly evolving spectrum of cyber threats.

But this is likely to change.

Security teams need to be prepared to contribute to more than the governance aspect of ESG — they need to contribute to the environmental goals of the organisation as well.

This is starting to be seen in several initiatives. These include the adoption and implementation of more energy-efficient security systems, together with a greater emphasis on proactive and preventative security.

Energy-efficient systems

As with other types of information technology, it continues to be the case that the efficiency of security systems is improving over time with each iteration or update.

A key performance indicator is the energy consumption per gigabit of data throughput for a piece of equipment. Next-generation security gateways are a security-specific example of hardware that continues to get more efficient with each new generation of the technology.

As a case in point, a recent Check Point ESG report showed that a current-generation security gateway uses 73% less power consumption per throughput (Gbps) compared to the previous model. This reduction comes alongside a 112% improvement in threat prevention capabilities, meaning the newer version is more efficient than its predecessor in multiple contexts, not just in energy usage concerns. And, to be clear, this kind of improvement is seen consistently between versions of systems.

This illustrates that next-generation security technologies can simultaneously enhance protection and energy efficiency. By aligning to this cadence of technology upgrades, organisations can consistently reduce their environmental footprint while maintaining effective security controls.

Proactive detection and remediation

Another beneficial strategy when seeking to run security operations more efficiently is to focus more on preventative and proactive forms of security.

The logic here is that reactively dealing with security incidents is an intensive exercise. It is taxing on the individuals that have to perform this work, but also in financial terms. We know that the financial implications of a breach continue to increase over time. One aspect of financial implication is the energy-intensive processes such as restoring backups, along with rebooting, restoring and/or rebuilding entire systems.

Clearly, energy efficiency is not the primary goal of incident response. But from a broader ESG perspective, there is interest in organisations having strong cyber risk and security controls together with layered protections in place to mitigate against the risk of an attack, and/or to detect and isolate any infected infrastructure early on, such that any financial, productivity and bottom-line costs can be avoided. As energy is a considerable financial input to IT costs, it makes sense not to add to these costs due to a cyber incident taking place.

Preventative measures are also required because some existing and emerging types of attacks can run up big energy bills if they go undetected. Cryptomining malware, for example, remains a persistent threat despite its peak in 2018 when it affected 40% of analysed organisations. Even recently, malware such as XMRig has been detected targeting gaming engines. The collective energy consumption of cryptomining is estimated at a staggering 125 terawatt-hours annually — highlighting the need to quickly detect this kind of malicious payload before it can be used to run up a big bill.

Data poisoning in AI systems represents another emerging concern. These attacks compromise machine learning models, often requiring complete retraining to remediate — an extremely energy-intensive process. As organisations increasingly rely on AI-powered tools for decision-making, protecting these systems also means avoiding redundant and costly training cycles that consume substantial computational resources.

The combined benefit

Cybersecurity is more than a governance play — it also has a growing role in helping meet the environmental aspects of an organisation’s ESG strategy. By considering the energy implications of security operations, maintaining infrastructure that is both secure and sustainable, and prioritising a proactive security approach, organisations can protect both their business interests and environmental resources.
